ASCE COPRI Seattle Dinner Meeting - January 23, 2019
Topic:
Floating Offshore Wind Power
Description:
With the rapid growth of wind energy in recent years, developers will increasingly rely on offshore sites to meet demand. Offshore wind energy sites have a number of advantages over their onshore counterparts, including advantageous wind characteristics, fewer limitations on turbine size and proximity to coastal urban centers where demand is concentrated. Against those advantages must be weighed the disadvantages of relatively expensive construction and installation, severe environments, longer export cables and higher maintenance costs.
Wind energy technology is following a similar trend to the oil and gas industry during the latter half of the 20th century, moving from onshore to fixed-bottom offshore to floating technology, as technology develops and easily-developed sites become less available. Offshore floating wind energy is currently a young industry, and as such, there are a considerable number of competing platform designs, each designed to best balance the constraints of maximum energy production, maximum reliability, minimum capital expenditure and minimum operational expenditure to arrive at the minimum levelized cost of energy (LCOE).
Floating offshore wind is a marriage of two very distinct technologies: wind turbines and offshore platforms. Analysis, design and regulatory frameworks for these two technologies have developed independently, with very different sets of environmental assumptions, constraints and analysis approaches. The lack of a standard set of industry-accepted coupled loads analysis tools and methodologies is recognized as an impediment to the further maturation of this industry, and development of such tools is an on-going international effort. John will discuss Glostens support of these efforts over the past seven years.
Glosten has developed a tension-leg platform (TLP) design, for use in moderate to deep water depths. The design was developed during a FEED study for the Energy Technology Institute (ETI) in the UK, and involved contributions from a large international team of a turbine manufacturer, a shipbuilder, an offshore installation contractor, a synthetic fiber tendon manufacturer and a classification society. John will discuss the design, technological developments and loads analysis efforts for this platform.
Speaker:
John Cross-Whiter, PE
Senior Ocean Engineer, Glosten
John Cross-Whiter is a naval architect and ocean engineer with over 30 years of experience in the analysis, simulation and testing of ships and offshore structures. He has been with Glosten since 2006, and leads Glostens efforts in marine simulation and dynamic analysis. John led Glostens loads analysis team during the PelaStar development project. Prior to joining Glosten John worked at model testing facilities in Europe, performing aerodynamic and hydrodynamic model tests on a wide variety of ships and offshore structures.
